Billy Black is the father of Rachel, Rebecca and Jacob Black. His wife, Sarah Black, died in a car accident when Rachel, Rebecca, and Jacob were young, and he is confined to a wheelchair because of diabetes. He is Charlie Swan's best friend.

Sarah Black (née Wilde) is the deceased mother of Rachel, Rebecca and Jacob Black, and the late wife of Billy Black. She died in a car accident when her children were young. It is said that her body is injured so badly they had to seal her coffin shut.

Rachel Black is the older sister of Jacob Black, twin sister of Rebecca Black and the daughter of Sarah and Billy Black, and sister-in-law of Solomon Finau. After her mother died in a car crash, Rachel received a scholarship to University of Washington in Seattle, and moved away from her father and brother. In Breaking Dawn, however, she has finished her degree and moved back to La Push, where she is imprinted on by Paul Lahote.

Rebecca Black (later Finau) is the younger twin of Rachel, older sister of Jacob, and daughter of Billy and Sarah. She married Solomon Finau, a Samoan surfer, when she was eighteen and moved to Hawaii, partly to get away from the memory of her mother, who died in a car crash. Like her mother, she is an artist, though she prefers to use oils. They travel frequently for Solomon's competitions. Rebecca is now the only person in the family who knows nothing about the existence of vampires and shape-shifters.
